I am unable to replicate the behaviour to say is happening. The macro is not limited in the number of rows it can process. As per your table specification in post #3, however, only columns 3 and 4 are processed. The problem may be the result of your last row having the first two columns merged, but it's not apparent from the image you posted whether that is the case or there's just no border there.

PS: Kindly stop posting oversize images - we're not blind and all you're achieving is making your posts harder to read. I have resized your images to something more sensible.
